- Acting for Two:
- Development Hell: The second season of the anime. Announced at the end of the first season in 2009, and no more news since then. Producer Jiyū Ōgi leaving AIC to help start Production IMS in 2013 didn't help matters either.
- Real-Life Relative: Then-real-life couple Andrew Love and Emily Neves respectively provide the voice of Keizou Kirishima and his daughter Kotone.
- Stillborn Franchise: The anime was supposed to have a second season, but there never was.
